TO ALL WHOM IT MAY GONCERN:.

I Beit known that I, ALBERT B, BEAN, o f New Haven, in the county of New Haven, and State ofrConnec-` "ticut, have-invented a new Improvement in Knife-Sharpener; and Ido hereby dcclarethe following, `when taljren` connection with the accompanying drawings, and the letters of reference marked thereon, tobe a full, clear,"l l t i i and exact description of the same, and which said drawings constitute part of this specification, an`d`rep`re`` sent, in

Figure 1, a perspective view, Figure 2 a. section on'line a: x, and in FiguresS and 4 the Sharpeners detached. This invention relates to an improvement in the arrangement of cutters for sharpening knives, and consists l vin forming the cutters so that they may be changed to present new and fresh edges, co'mbinedwith thc peculiar,

marinerpf `securing the cutters when so changed, and also in combination with a knife-Sharpener with a hone)` or strap. i

Y To enable others to construct and use my improvement, I will proceed to describe the same, as illustrated g i in the acconipanying drawings. i

A is the hone or strap, its surfaces provided with any material to aid in finishing the edge ofthe knife, and isformed with a handle, B, for convenience in use. Near the handle, upon o ne of its angles, is placed arghtj" l angular slotted piece of metal, C, formed so as to receive in each ofv its slots a block, D E. d heseblocks are formed of an equal thickness, and square, so that they may be removed from the slot andY replaced, presenting. a new edge to the centre, until all the edges have cach been presented, thatjis, makingeight changes each, and they-are setrint'o their respective slots, as seenin fig. 1, sons to leave a converging openpspace between the two. the edges meeting at a short distance from the top, and the blocks are secured ih the following manner: i

The first block, E, is inserted, then the block D,'so as to setagainst the bleek E, and held by a cam, a, as seen n` fig. 2. The block D is bound hard againstthe block` E, so as 'to hold them both rmly in their proper in l` position. A To remove either of the blocks, release the' cam, and when the blocks are again replaced, return the i,

I cam as before. After having drawn the knife through the Sharpener to reduce the edge, it is finished by drawing a few timesover the strap. i p Having thus fully described my invention, what I claim as new and useful, and desire to'securc by Letters Patent, is i i The combination of the blocks E and D, of the form described, with their holderC, when secured therein so p as to be adjustable to present new edges, substantially as and for the purpose specified. i e A ALBERT E. BEAN.` l
